Find the length of a side of a square whose perimeter and
area have the same value.
help?
perimeter of a square is P=4s & the area of a square is A=s^2

Reiny
so you know
s^2 = 4s
s^2  4s = 0
s(s4) = 0
s = 0 or s=4
So the side is 4 units
check:
area = 4^2 = 16
per. = 4(4) = 16

Why did you stop? You were on the right track but forgot to make use of the most important piece of information given.
The perimeter of a square of side "s" is P=4s.
The area of the same square is A = s^2.
Find the length of a side of a square whose perimeter and area have the same value.
P = A = 4s = s^2
Can you take it from here?
